Review request for hive, Ashutosh Chauhan, Navis Ryu, Sushanth Sowmyan, and
Swarnim Kulkarni.
Bugs: HIVE-6584
https://issues.apache.org/jira/browse/HIVE-6584
Repository: hive-git
Description
-------
HBASE-8369 provided mapreduce support for reading from HBase table snapsopts.
This allows a MR job to consume a stable, read-only view of an HBase table
directly off of HDFS. Bypassing the online region server API provides a nice
performance boost for the full scan. HBASE-10642 is backporting that feature to
0.94/0.96 and also adding a mapred implementation. Once that's available, we
should add an input format. A follow-on patch could work out how to integrate
this functionality into the StorageHandler, similar to how HIVE-6473 integrates
the HFileOutputFormat into existing table definitions.
See JIRA for further conversation.

Unit tests, local-mode testing, pseudo-distributed mode testing, and tested on
a small distributed cluster. Tests included hbase versions 0.98.3 and the HEAD
of 0.98 branch.
